Sand Cooling Drum for Efficient Sand Cooling

The L32 Series Shakeout & Cooling Rotary Drum is an integrated post-casting system that combines shakeout, cooling, and primary cleaning in a single unit—engineered for high-volume, continuous foundry lines. Hot molds (with castings and sand) enter the rotating drum, where centrifugal force, lifter-bar impacts, and internal airflow work together to rapidly disintegrate the mold, cool castings to ≤80°C, and remove loose surface sand. With a capacity of 30–150 tons/hour, it is widely used in automated plants producing automotive engine blocks/heads, ductile iron pipes, and heavy machinery components—significantly reducing downstream cleaning workload and improving line synchronization.

Infeed: Hot molds (boxed or boxless) are fed into the drum via conveyor.
Shakeout: The drum rotates at 4–8 rpm; internal lifter bars repeatedly lift and drop the molds, breaking apart sand from castings.
Cooling: Ambient air (optionally forced by blower) flows counter-current through the drum, extracting heat from castings and sand.
Primary Cleaning: Tumbling action causes castings to collide, dislodging adhered sand.
Discharge: Cooled castings and reclaimed sand are separated via built-in grates or external classifiers and routed to respective conveyors.

3-in-1 Functionality – Space & Cost Efficient
Replaces conventional "shakeout machine + cooling conveyor + vibrating screen"—reducing equipment count by 40% and lowering CAPEX & footprint.

Gentle Shakeout – Casting Damage Rate <0.5%
Low RPM + curved lifter bars + impact-absorbing liners prevent cracking—ideal for thin-wall, complex parts (e.g., cylinder heads, turbo housings).

Efficient Cooling – Outlet Temp ≤80°C
Counter-flow air cooling with 3–8 min residence time cools castings from 400–600°C down to ≤80°C—safe for robotic handling or manual transfer.

Fully Enclosed – Ultra-Low Dust Emissions
Sealed drum with flexible curtains at inlet/outlet and dust extraction ports (DN250–DN400). Fugitive emissions ≤5 mg/m³—compliant with GB 39726 and EU BREF.

Wear-Resistant & Easy Maintenance
Drum lined with NM500 steel or ceramic-composite panels—service life ≥3 years. Modular end caps allow bearing replacement without full disassembly.

Automotive Engine Plant: Integrated shakeout & cooling for blocks, heads, crankcases
Ductile Iron Pipe Foundry: High-volume processing of DN80–DN1200 fittings
Construction Machinery: Bucket teeth, track rollers, housings
Smart Green Foundry: Core post-processing unit in "lights-out" casting lines
